【中文标题】无法判断 Vue 项目是处于调试模式还是 Visual Studio 的发布模式【英文标题】：Can't tell if Vue project is in debug more or release mode for Visual Studio 【发布时间】：2019-09-08 05:58:37 【问题描述】：

我正在使用 Visual Studio 构建这个 Vue 应用程序，无论构建模式（调试/发布）如何，我仍然会在控制台中收到以下消息。

您正在开发模式下运行 Vue。确保在部署生产时打开生产模式。在https://vuejs.org/guide/deployment.html查看更多提示

有没有办法知道我是否真的处于发布模式，或者 Vue 是否只是在向我抛出该消息？

我知道这通常意味着 JS 文件已被缩小，Vue 应用程序是这种情况吗？

我不确定这是否有帮助，但这是我的 packages.json 文件

【问题讨论】：

你运行了什么脚本？（在 package.json 中）不确定！这是我继承的前同事项目。我该如何检查？我将发布 packages.json 文件。 【参考方案1】：

正如您发布的Vue.js deployment guide 所建议的那样，请检查您的webpack.config.js 并确保在部署应用程序时使用正确的mode 目标production 环境。

在 Webpack 4+ 中，你可以这样做：

module.exports = 
  mode: 'production'

但在 Webpack 3 及更早版本中，您需要使用 DefinePlugin：

var webpack = require('webpack')

module.exports = 
  // ...
  plugins: [
    // ...
    new webpack.DefinePlugin(
      'process.env.NODE_ENV': JSON.stringify('production')
    )
  ]

准备就绪后，您只需运行 npm run build 即可开始捆绑您的模块。
